An'ris Errne ATTACHMENT.

Application filed December 26, 1916. SerialNo. 138,937.

To all whom it may concern: I

Be it known that I, PERRY A. SKILEs, a citizen of the United States,residing at Surrey, in the county of l/Vard and State of North Dakota,have invented certain new and useful Improvements in AntislippingAttachments, of-which the following is a specification. Y

T his-invention relatesgenerally, to boots and shoes, and. the inventionhas moreespecia'l reference to an improved anti-slipping attachment forthe soles and heels of boots and shoes.

The invention has for its principal object to provide an anti-slippingattachment which can be instantly engaged with the soles and heels offootwear and will enable the wearer to safely walk upon icy or snowcovered ground without falling.

As an object of equal importance, the invention aims to provide ananti-slipping at-- tachment which can be used in outdoor sports such asbaseball, sprinting, jumping and the like, whereby the athlete will been abled to gain a firm footing when in action.

Still further, the invention aims to provide an, anti-slipping devicewhich may be readily detached from a shoe heel or sole, thus permittingordinary walking shoes to be used. 1

The improvements in the details and arrangements of parts will beapparent from an inspection of the accompanying draw ings, in connectionwith the specific description hereinafter contained, and wherein thepreferred embodiment of the invention is disclosed for the purpose ofimparting a full understandingof the invention.

In the drawings:

Figure 1 is a side elevation of the improved antislipping attachment asapplied to a shoe heel and sole,

Fig. 2 is a bottom plan thereof; and

Fig. 3 is a tran'sverse section taken on the line 33 of Fig. 2.

Referring more specifically to the drawings, wherein like referencecharacters designate corresponding parts in the several views, thepresent improvements may be stated to embody engaging members 1 and 2,portions of which are provided with hooked members 3, whereby theengaging members 1 and 2 may be securely engaged with the shoe sole.Calks,.generally indiated y t numeral e are arra ged up nthe forwardends of the engaging members 1 and 2 and are formed by bending portionsgaging members 1 and2, preferably intermediate the ends thereof and areadapted to receive therethrough, connectingarms 9, the

oppositee'nds of'jwhich are screw threaded 'as at 10 and'have' turnedinto engagement therewith, adjustable locking'nuts 11, the

I of the saidmembers upwardly and beveling said locking nuts beingscrewed againstfthe lugs S.

Vith a view toward providing means whereby the engag ng members 1 and 2-may 7 7 be clampedvupon a shoe sole. the adjacent ends of the arms-9 arebent inwardly as at 12 and are pivotally connected to a channeled lever13, by means of suitable cross pins or rivets let which are secured tothe op.- posite wallsof said channeled lever. To permit the lowerconnecting arm 9 to be pivotally connected to the lever. 13 slightlybeyond the pivotal point of the upper arm 9',

an elongated slot 15 is formed in'the) lever whichreceivesthe curved orbent end of the said lower arm. By thus arranging and connecting thearms 9;, it is evident that when the lever 13 is in one position, theconne'cting' arms together with the engaging membersland 2 will be'inextended posi tions; However, when the lever is swung into the positionshown in Fig. 3 a pull will be imparted to each of the connecting armsand they'will be caused to assume positions reverse to the positionstaken when the members 1 and 2 are in extended positions. Furthermore,by mounting the pivots of the connecting arms out of horizontalalinement upon the channeled lever 13, the said lever will be permittedto be maintained in locked position. In applying the attachment to solesof varying widths, the locking nuts 11 formed upon the peripheral edgethereof,

hooked engaging members 20, whereas, the opposite edge thereof isprovided with a plurality of ealks 21, formedin a manner similar to thecalk 19. To secure the engaging members 16 and 17 to the shoe heel, anupwardly bent apertured lug 22 is formed upon the member 17, preferablyintermediate the ends thereof, while an opening of suitable size isarranged transversely of the call: 19. Connecting arms 9, similar tothose as used in. conjunction with the sole attachment are engaged withthe apertured lug 22 and the call; 19 and are supplied with a locking.nut 11. The adjacent ends of the connecting arms are connected to thelooking lever 13, which, when operated in the manner as hereinbefore setforth, will efliciently clamp the said members upon the shoe heel.

When desired, it is evident that the anti- 7 slipping attachments forboth the shoe sole and heel may be readily removed therefrom;furthermore, if desired the attachments may be applied to practicallyany form of shoe and when engaged therewith will ofier a positive and.durable anti-slipping means.

Still further embodiments than those herein especially defined may beresorted to such as conditions or preference may dictate, as may be inkeeping with the hereto appended claims.

I claim: A

1. An ice creeper including sole pieces, a

ing a threaded adjusting means at one end in connection with the solepieces, the other ends of the connecting members being pivoted to thelocking lever and shaped to avoid each other when the ice creeper islocked, the pivot being arranged so that one is 10 cated above the otherto hold the locking lever locked. i

2. An ice creeper including sole pieces and a locking lever, andconnecting elements between the sole pieces, the connecting elementsbeing pivoted in disalinement with the the connecting elementswithrespect to the sole pieces. 7,

4.- An anti-slipping attachment of the character described, includingoppositely disposed engaging members, calks formed integrally with saidengaging members, connecting arms adjustably secured to said engagingmembers, and a locking lever connected to the adjacent ends of saidconnecting arms for moving the same into and out of clamping engagement.

5. An antislipping attachment of the character described, includingoppositely disposed engaging members, Lip-struck calks formedupon saidengaging members, connecting arms adjustably secured to said engagingmembers, and a channeled locking lever having an elongated slot therein,one of said connecting arms being pivotally secured to one end of thelocking lever andthe other of said connecting arms extending through theelongated slot in the lever and pivotally connected thereto at a pointout of horizontal alinement with the pivot of said first connecting arm,whereby the engaging means may be moved to and maintained in clampingposition. locking lever, and connecting members hav- In testimonywhereof I affix my signature in presence of two witnesses.
